Water is Water is Water
You might not realize this, but animals need to drink water. This might be obvious when you think about dogs, horses, and even cats. But when you think about other non-conventional animals like squirrels or birds, you mightn’t have ever realized they also need water.
Apparently, birds definitely do drink water, and seagulls nonetheless. There is something ironic about seagulls needing to drink water considering they live around water all day, granted that water is saltwater so they can’t actually drink it. But this bird doesn’t care very much for signs.
